Lub hauv paus ntsiab lus ntawm high-txhais twisted khub transmitter
Siv ob txoj xov hluav taws xob sib kis los xa cov cim video, lub hauv paus ntsiab lus yog:
1. Lub teeb liab video li ib txwm ua yog tsis sib npaug ntawm lub teeb xa xov tooj bandband, tsim nyog rau kev sib kis hauv cov kab tsis sib xws xws li coaxial cable. Cov twisted khub cable yog sib kis tau kis cable. Nws yog qhov tseeb vim tias qhov kis tau sib luag thiab sib ntswg ntawm hom ntawm cov cable uas qhov sib kis kis tau muaj lub zog muaj peev xwm tiv thaiv kev cuam tshuam, yog li nws tsim nyog siv txoj kev sib kis los xa cov cim video. Cov teeb liab video yuav tsum hloov pauv mus ua lub teeb liab sib npaug.
2. Lub vev xaib video hloov pauv rau hauv hom sib npaug tuaj yeem kis ncaj qha rau ntawm cov kab sib kis ntawm cable, thiab nws tsis yooj yim cuam tshuam los ntawm ntau yam kev cuam tshuam. Thaum nws los txog rau lub chaw nres tsheb saib xyuas, txij li cov chaw nres nkoj nkag ntawm cov cuab yeej saib xyuas feem ntau xws li cov yeeb yaj kiab thiab cov zaub tso tawm tsis sib npaug, nws yog qhov yuav tsum tau hloov lub teeb liab sib kis dhau ntawm cov sib koom tes mus rau hauv lub teeb liab tsis sib npaug. Ntawd yog, yuav tsum tau siv cov twisted khub cable hloov cov kab xev xaib kom xa cov cim video, nws tsuas yog tsim nyog ntxiv cov ntsuas qhov sib npaug / tsis sib npaug (xovxwm-hom cov dav hlau) ntawm lub hauv ntej thiab tom qab kawg ntawm lub cable.
3. Lub tshuab hluav taws xob sib txuas yooj yim tshaj plaws yog qhov sib txuas ntawm cov yeeb yaj kiab sib txig sib luag inductance coil rau ntawm lub nplhaib sib nqus nrog lub siab sib nqus flux thiab siab bandwidth. Qhov no feem ntau hu ua passive converter. Nws tsuas yog ua lub luag haujlwm ntawm kev sib npaug / tsis hloov pauv. Nws yog cov khoom siv passive. Nws yuav tsis coj tshiab distortion los yog ua suab nrov, tab sis nws yuav attenuate lub teeb liab mus rau ib qhov twg.
4. Thaum lub teeb liab video xa mus rau ntawm cov khub sib kis ntawm cable, kev sib txuas ntawm lub teeb liab, tshwj xeeb tshaj yog kev saib xyuas ntawm qhov muaj teeb meem loj, yog qhov tshwj xeeb, yog li cov teeb meem sib npaug ntawm cov video tom qab sib tw kis tau kis yuav tsum tau kho kom nrov zog los ntawm kev txuas hluav taws xob hauv dav dav Thiab nyob rau hauv teb rau kev saib xyuas ntawm lub teeb liab, tshwj xeeb tshaj yog cov teeb liab loj siab, nws tau ua kom zoo thiab rov qab, thiab tom qab ntawd hloov mus rau hauv lub teeb liab tsis sib luag rau kev siv los ntawm cov ntsuas thiab lwm yam khoom siv nqes. Feem ntau qhov ntsuas suab nrov no hu ua kev sib tw khub kis, uas yog lub luag haujlwm ntawm ua kom nrov nrov thiab them nyiaj. Feem ntau, nws muaj ob lub hwj chim kho nyob rau nws kom kho qhov nce ntxiv ntawm txhua lub suab nrov ntxiv thiab cov nyiaj them rov qab rau cov khoom siv hluav taws xob ntau raws li qhov xwm txheej tiag tiag.
